Sure, I could always say, "Email that to me," but then there's the hassle of handing over my email address and relying on the company rep to remember.

In an ideal world, I'd just wave my phone at the info and presto: instant copies downloaded to my device.

That's the idea behind , which uses QR codes to share documents, presentations, and the like.

It works like this: Using TagMyDoc's tools, you add a QR code to, say, a Word or PowerPoint file. That document gets tagged and uploaded to TagMyDoc's cloud storage, where it effectively becomes an on-demand file: Anyone who scans the code from your hardcopy immediately gets a copy.

So, for example, if you're giving a presentation, you might want to give everyone a copy of the slide deck. Instead of printing, collating, clipping, and carrying all that paper, you can simply tack a TagMyDoc code onto the final slide. Then everyone just scans the code on their phone and boom, they've got their copy.
